INSTALLATION AND TORQUING
1. Matching Nuts. Matching nuts require a minimum height equal to the basic diameter of the bolt. The same is true
of tapped holes. In tapped softer materials, the depth of the tapped hole should be 1-1/2 times the basic diameter
of the bolt.
2. Threaded Protrusion. In all installations, bolts, studs, and screws must extend through the nut at least a length
equivalent to two complete threads. This applies to both self-locking and plain nuts.
3. Torquing Self-Locking Nuts. To obtain the correct recommended torque value on self-locking nuts, the nut must
be tightened until it is one turn from the beginning of seating. At this point, if the torque is less than 1/3 of the
